Plants!

A living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, typically growing in a permanent site absorbing water and inorganic substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll

What is a plant?

ReproductionPlants have a reproduction system just like us. Only theres can be asexual or sexual. Sometimes there pollen is spread by wind, or sometimes by other insects. Thats how they get more of there species to grow, and thats why plants don't die out.

There are 2 main kind of leaves, Broad and Narrow leaves. Leaves can tell a lot including the leaf attachment. Leaf attachment is the pattern by which leaves are attached to a stem or twig is also a useful characteristic in plant identification.

LEAVES

Pholem

Root and shoot system.

Xylem and pholem in a plant is like the vascular system in a vertebrate. The xylem and phloem being the veins. Of course there are some minor differences. Like for example the vascular system has way more parts then just veins.

Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes.

Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.

Xylem and Pholem.

The Flower:The flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs).

Adaption

Fertilization:Pollen must fertilize an ovule to produce a viable seed. This process is called pollination, and is often aided by animals like bees, which fly from flower to flower collecting sweet nectar. As they visit flowers, they spread pollen around, depositing it on some stigmas. After a male's pollen grains have landed on the stigma during fertilization, pollen tubes develop within the style, burrowing down to the ovary, where the sperm fertilizes an ovum (an egg cell), in the ovule. After fertilization, the ovule develops into a seed in the ovary.
