What is the cambium?
The part of the plant that separates the phloem from the xylem.
What are root hairs?
Thread-like parts of cells on the surface of a root.
What is a rootcap?
The thin covering made up of cells that protects the root tip as it grows.
What is the phloem?
The tube or tissue through which water and minerals flow down the leaves of the plant.
What process STORES energy?
What is the cuticle?
The waxy coating that the epidermis secrets to keep water inside the leaf.
What is the cortex?
The place inside of the root where food is stored.
What process RELEASES energy?
The process of RESPIRATION releases energy.
Sugars and oxygen join to produce water, carbon dioxide and energy; respiration occurs in plants and animals.
Define xylem.
The tube or tissue through which water and minerals flow up through the plant.
What is the epidermis?
The outermost layer of a root, stems or a leaves.
Give 4 examples of LEAVES of plants we use for food.
Spinach, herbs, cabbage, lettuce.
Tell me 4 facts about stems.
1)Stems support flowers and leaves
2)Stems store food
3)Stems do NOT absorb water
4)Stems are part of the process of transpiration
What is transpiration?
The process where water evaporates from the leaves and more water moves up through the plant to replace water.
Where do aerial roots grow?
Aerial roots grow in wet climates.
What is photosynthesis?
The process by which plants make food. Carbon dioxide and hydrogen from water and sunlight come into leaves, where they react with chlorophyll and produce sugars and oxygen. Sugar is stored in green plants and oxygen is released by the plants.
Give 4 examples of STEMS of plants we use for food.
Sugar, onion, asparagus, celery
What are chloroplasts?
The part of the plant cells where plants make their own food.
Give 4 examples of ROOTS of plants we use for food.
Sweet potatoes, horseradish, carrots, beets
Tell me 2 facts about aerial roots.
Aerial roots don't touch the ground and they get the moisture they need from the air.
