Qualities of Plants

Plants are different from animals; they use sunlight, water, and carbon dioxide to make their own food and have roots and leaves. Many plants are vascular, which means they have special tubes that carry food and water to all parts of the plant. Four common types of plant phyla are mosses, ferns, conifers, and flowering plants.

Qualities of Plants

Ferns Flowering PlantsMost ferns have leaves that look like feathers and are vascular plants, which can grow larger than nonvascular plants. Vascular plants have tubes that carry food to parts of the plant that are high off the ground. Mosses and ferns use spores to reproduce, which are tiny cells that can grow into plants.

There are about 230,000 species of flowering plants they are all vascular. These plants use their flowers’ seeds to reproduce. Mosses, ferns, and conifers don’t produce flowers.

Mosses

Mosses grow on trees or in shallow streams and are very small. Mosses are not vascular and have tiny parts that looklike leaves. They don’t have flowers or seeds.

Conifers

Pine, fir, and spruce trees are all conifers that have special leaves called needles. Conifers are vascular plants and reproduce using cones and seeds.

Neither Plant Nor Animal

Many organisms do not belong in either the plant or animal kingdoms and some of these organisms can move on their own like animals, but they make their own food like plants. Some organisms are made of one cell and these can only be seen through a microscope. Some of these microscopic organisms can cause disease and others can be helpful. Like plants and animals, all these organisms need food, water, and a way to remove waste. Many also need carbon dioxide or oxygen.

Debates in Classifying

The classification system has changed over the years because scientists find new organisms.One classification system used today has six kingdoms, which include plants, animals, fungi, protists, eubacteria, and archaebacteria.Fungi, such as mushrooms, are not plants because they cannot make their own food because they absorb food from the material they grow on. Yeast are single-celled fungi and to reproduce, each cell divides into two cells.Protists such as algae are single cells and are food for many animals. Some live in the digestive systems of some animals, like termites and cows. They help these animals digest plants they eat. Eubacteria are single cells and can have many different shapes. Some have tails that move them through water.Archaebacteria are single cells and can survive in environments that are deadly for most other organisms. They can live in hot acid springs or in very salty water.

Answer questions in your Science Journal.

1. How would you classify a plant that has seeds, is vascular, and has needle-like leaves?

2. How do protists help some animals?

3. How are the needs of single-celled organisms similar to the needs of plants or animals?

4. Compare the fungi and protist kingdom.
