CAN PLANTS MOVE?
Plants are one of the five kingdoms of living things. They are made up of many cells and are usually rooted in soil. Their green leaves capture sunlight to make food by

PHOTOSYNTHESIS , providing food either directly or indirectly for most other living things on Earth, as well as life-giving oxygen.
The carnivorous Venus flytrap, which grows in very poor soils, takes essential minerals from insects. The ends of the plant’s leaves form a trap of two pads. If an insect lands on the pads, the trap snaps shut. The plant digests the insect and absorbs its minerals.

WHICH ARE THE BIGGEST PLANTS?
Trees are the biggest of all plants. They grow so large because they are supported by a woody trunk that increases in width as the tree grows taller. The tallest tree, and the biggest living thing, is the Californiancoast redwood, which reaches over 360 ft (110 m).

WHY DO PLANTS HAVE ROOTS?
Plants have roots for two main reasons. Roots anchor the plant in the soil, and prevent it from being blown away by strong winds. They also take up water and minerals, such as nitrogen and sulfur, from the soil. Plants need water to replace that lost by TRANSPIRATION , and minerals to make substances essential for life.

HOW DO PLANTS DEFEND THEMSELVES?
Plants cannot escape from hungry plant-eaters, but they have evolved a wide range of defenses. Some have thorns or spines that cut into an animal’s skin and will pierce its mouth if eaten. Others produce chemicals that taste terrible and maybe poisonous. Some have tiny hairs on their leaves that stop leaf-eating insects from reaching the leaf’s surface.

PLANT CLASSIFICATION
So far, scientists have identified over 300,000 species of plants. These are divided into two groups:
Plants that reproduce using spores, including mosses, ferns, horsetails, and four other phyla.
Plants that reproduce using seeds, including flowering plants and conifers.
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
TRANSPIRATION
Leaves constantly lose water by evaporation through tiny pores, or stomata, that also let carbon dioxide into, and oxygen out of, the leaf. Thiswater loss, called transpiration, creates a force that helps draw up more water from the roots.
