To Accompany Your Biology Curriculum

Biology Resources:

Biology is the science that focuses on the study of life, living organisms, cells, taxonomy, genetics, ecology, populations of living things, ecosystems, plants, photosynthesis, cellular respiration, invertebrates, vertebrates, fungi, bacteria, and other topics.

I created this series of biology webpages to accompany the biology curriculum we were using in the homeschool biology class I taught. The webpages contain information, videos, and labs that may be helpful for students studying biology. The pages often build on one another, so it's best to do them in order unless you are already familiar with the previous biology topics.

Have fun!


Biology Resources

Protists

Protists are organisms that don't really fit into any other category, so they're all put together in the Kingdom Protista. They have a lot of differences between them. Some protists, for example, are like plants in that they engage in photosynthesis. Some protists are like fungi in that they absorb their food, and some protists are like animals in that they eat their food.

Protists do have some things in common though. For example, they live in moist places. Also, they don't form embryos to reproduce.

How do protists move?

  • Some move via their flagella.
  • Some move via pseudopodia.
  • Some move via cilia.

Did you know that some types of protists can cause diseases, including dysentery, toxoplasmosis, giardiasis, and malaria?

Protists: Paramecium, Amoebas, Algae, Diatoms, Euglena, and Others

On this page, we explore the world of protists, such as paramecium, algae, Euglena, plasmodial slime molds, and amoebas!

The Fungi Kingdom

The Fungi Kingdom

The fungi kingdom includes mushrooms, molds, rusts, yeasts, and many other organisms. They are made up of slender filaments. Fungi have an interesting way of eating: they secrete digestive enzymes onto something such as leaves or dead animals and then absorb the decomposed nutrients from it. Most fungi reproduce via spores.





Unit 6 on Plants

Source

The Plant Kingdom

The Plant Kingdom

There are many different types of plants.

  • Nonvascular plants don't have vascular tissue (the tissue that transports water throughout a plant), and include plants such as mosses, liverworts, and hornworts.
  • Vascular plants do have the ability to transport water via vascular tissues and can be divided into three categories:
    • Seedless vascular plants such as ferns
    • Gymnosperms which are seed plants that make cones
    • Angiosperms which are seed plants that have flowers and fruit. Angiosperms can be divided into:
      • monocots - plants with only one seed leaf
      • dicots - plants with two seed leaves



The Animal Kingdom

An Introduction to the Animal Kingdom

The Animal Kingdom: An Introduction

Here are some of the characteristics that animals have.

  • They must find their food. They can not make it like plants.
  • They have muscle cells and can move.
  • Animals are multicellular.
  • The majority of animals are diploid, which means their gametes have only one set of chromosomes, but when two gametes unite to make a new living creature, they baby will have two of every set of chromosome. This allows for new combinations of genes.
  • Animal cells do not have a cell wall. This is part of the reason as to why they can move.
  • Although some animals, such as sponges, are asymmetrical, many animals have either radial symmetry (like a starfish or a sea anemone) or bilateral symmetry (like a puppy or a human).

Invertebrates

Invertebrate animals don't have backbones.

Sponges are one type of invertebrate animal. Even though sponges don't have a backbone, they do have a type of skeleton. It's made out of spicules which are tiny needles of calcium carbonate or silica.

Did you know that sponges are animals, and not plants?

Did you know that sponges can regenerate when they are cut into pieces? This means that each piece will grown into a brand new sponge!

Sponges are Simple Animals

Jellyfish are cnidarians, which are invertebrates in the animal kingdom.

Cnidarians (such as jellyfish)

Although I surely would not want to be stung by a jellyfish, I think they are fascinating creatures! Have you ever watched them float? They're beautiful!

Cnidarians, which includes jellyfish, sea anemones, and some other ocean life, have radial symmetry.

Cnidarians can have a medusa shape (often resembling an umbrella) and be free floating, or they can be tube-like polyps, most of which are attached to rocks or other objects in the water.

A particularly fascinating cnidarian is a Portuguese man-of war. A single one can contain 1,000 meduses and polyps.

Mollusks

Mollusks Are Invertebrates

Mollusks are invertebrate animals such as snails, squids, octopuses, and scallops. Each mollusk has three major parts to his body: a visceral mass, a foot, and a mantle.

Have you ever heard of a Christmas tree worm? I think they may be one of the prettiest types of worms...

Arthropods

The Characteristics of Arthropods

Arthropods are animals such as insects, scorpions, spiders, shrimp, and crabs.

Arthropods have:

  • jointed appendages,
  • segmented bodies,
  • and exoskeletons.

Echinoderms

Echinoderms are spiny invertebrates that live in the ocean. Examples of echinoderms include sea stars, brittle stars, sea urchins, sand dollars, and sea cucumbers.


See the outstretched arms on the crinoid shown here? He's using them to catch plankton to eat!

Seahorse

Vertebrates

Vertebrates are animals that have a backbone. There are many types of vertebrates, including fish, amphibians, reptiles, birds, and mammals (including people).

Here's the first page of the vertebrate unit.

The Characteristics of Fish

By the way, what do you think? Are seahorses really a type of fish?

      Terrific Biology resource page! I have a funny story about taking Biology in college. My uncle was a professor at my college - teaching Zoology and Biology - and I signed up for his Biology class (because I was curious what he was like as a teacher!). He was NOT pleased, because no one knew we were related and he didn't want other students thinking he was 'playing favorites', so he was particularly hard on me that semester. I had to 'be prepared' with answers every class because he invariably 'called' on me! But, I passed the class! :-)

      @anonymous: LOL! Well, you may have a lot of wow, but you don't seem like a pig to me, KC! Thanks for the laugh though! I've been working really hard for the past few days on a new page in this biology series, and really appreciated taking time out for a laugh!! :-)
