Plants are made up of many different things. Most plants, have chloroplasts, which are small parts that are inside of a plant cell and they are the color green.
Plants also have cells, cell membranes, a nucleus, cytoplasm, a cell wall, petals, stamen, pollen, pistil and chlorophyll.
Plants are multicellular, which means that they have more than one cell, they are most of the time green due to the chlorophyll, they cannot move from place to place and they are autotrophs, which means they make their own food.
Plants are important because they are producers, which means that they produce things that help us. Plants, for example, help to produce oxygen.
There are two types of plant categories and these are vascular and nonvascular.
Vascular plants have two different tubes that help the plant to grow and survive. These two tubes are called the xylem and the phloem.
The xylem helps to carry water. Water is absorbed from the roots of the plant and the water is carried upwards.
It is important to note that the roots help to hold the plants into the ground and the roots also help to absorb water for the plants to be able to live.
The phloem carries the glucose, or the sugar, that is produced when photosynthesis happens.
Remember, the glucose is the food that the plants have that helps them to grow and the rest of the glucose is stored in the leaves of the plant. The phloem helps to carry the food.
Non-vascular plants do not have tubes such as the xylem and the phloem.
These types of plants still have to have glucose and water, and plants that are non-vascular, meaning they do not have tubes, are usually small and scrawny because they do not have the tubes to carry the glucose and water all through the plant.
Non-vascular plants get their water by osmosis, meaning they soak up the water. Some examples of non-vascular plants are mosses.
Most of the parts of a plant are used to help the plant to go through photosynthesis.
Remember, photosynthesis is when a plant makes its food from sunlight, carbon dioxide and water.
Plants have plant cells and these plant cells are too small to be seen without a microscope.
Each of these plant cells have a cell membrane which is a thin covering that surrounds the cell in order to keep the parts together.
The roots of the plant help the plant to absorb the water that is needed for the plant to survive.
The roots are important because they store access water for times when it is too hot and too dry.
The roots are also important for support, without roots, the plant would just fall over and would blow over if any wind came.
The center of the plant cell is called the nucleus. The nucleus is considered the control part of the plant cell, meaning that it tells the cell what kind of activities it is going to do.
The rest of the cell is covered with cytoplasm, a material that is like jelly.
Another part of the plant cell is the cell wall. The cell wall is the outside layer of the cell membrane and this is a strong layer that makes the cell have shape.
The plant cell also contains chloroplast, which are small, green organelles that are in the plant cell. The chloroplast helps to give the green color to plants.
Plants are useful for producing oxygen through cellular respiration.
Plants have small openings, called stomata, meaning more than one opening, or stoma, meaning only one, and they are small openings, mostly under the leaves, that help the plants to have gasses flow in and out of the plant, which is needed for photosynthesis.
The leaves of a plant are useful for capturing light energy in order to aid in photosynthesis.
Stomata cannot be opened all the time because water can come out of the stomata. The plants use guard cells to help determine if the stomata will be opened or closed.
If guard cells keep the stomata open, it can lose water but get gasses it needs.
If the guard cells close the stomata, it can keep water, but it will not be able to get the gasses it needs.
Most of the time at night, the plants close the stomata and preserve their water because photosynthesis cannot occur without light.
In the daytime, most plants open their stomata so they can get the gasses that they need to complete photosynthesis.
