How are stems different?
|
Some stems (not all) store food for the plant to use later, like the sugarcane and potatoes for example and also like the cactus stem which stores water. Not all stems grow up into the air. Some, like the stems of strawberries, grow along the ground. Some stems, like the potato, grow underground.

|
|
TRUE OR FALSE: Animal cells have a cell wall.
|
FALSE
Only plant cells have a cell wall. |
|
|
What is the EPIDERMIS?
|
Epidermis is the outer layer of a leaf. See page 24 of the textbook.
|
|
|
What is the job of a nucleus in the cell?
|
It is the control center of the cell.
|
|
|
The science of finding patterns among living things is called?
|
CLASSIFICATION
|
|
|
How are vascular plants different from nonvascular plants?
|
Vascular plants have tubes that carry food and water and minerals throughout the plant; nonvascular plants do not.
|
|
|
How are stems similar?
|
All stems support leaves. Some also support flowers.
Stems hold the transportation system for plants. This system lets water and minerals move from the root to other parts of the plant. |
|
|
What happens during the process of TRANSPIRATION?
|
When water evaporates from the leaf, more water moves up through the plant to replace it. This process is called transpiration.
|
|
|
Name three ways roots help plants survive?
|
1) Roots hold plants down in the ground. They help keep plants from getting swept away by wind and running water. 2) Roots draw up water and minerals from the soil. 3) Roots also store food for the plant.
|
|
|
What do all plants have in common?
|
All plants have cells with cell walls; most have roots, stems and leaves; all plants contain chlorophyll.
|
|
|
What is CHLOROPHYLL?
|
A green chemical in plant cells that allows plants to use the sun's energy for making food.
|
|
|
List three things plants need in order to live and grow.
|
water, sunshine, air
|
|
|
What is the CORTEX?
|
A layer just inside the epidermis (which is the outermost layer) of roots and stems. It stores food.
|
|
|
What is a xylem?
|
The xylem makes up the part of the transportation system that moves and minerals UP from the roots.
|
|
|
What is the phloem?
|
The phloem moves food from the plant's leaves to its other parts.
|
|
|
What is the cambium?
|
The cambium is a layer of cells that separates the xylem from the phloem. See page 22 in the textbook.
|
|
|
What is the ROOT CAP?
|
The root cap protects the young root tip as it grows into the soil.
|
|
|
What is CHLOROPLASTS?
|
Chloroplasts are the actual food factory of plants. They are located in cells between the layers of the epidermis.
