Study Flashcards
Three ways plants and animals are different?
Plants make their own food and animals depend on plants for their food. Plants don’t move, but animals have locomotion. Plants have cell walls and animals have cell membranes
Three major factors in climate that affect me plant growth?
Temperature, precipitation, and light
Three ways plants and animals are alike?
They have life cycles, carry on life processes, and must have food
Explain the warm season and give examples.
Plant in spring and die in fall (ex: tomatoes, beans, corn, squash, and rice)
Explain the cool season and give examples.
Plant in fall, grow in winter, and mature in spring (ex: oats, rue grass, vetch, and clovers)
The length of the light period in a day for a plant is its…
Photoperiod
What are the three groups on the basis of life cycle?
Annuals, biennials, and perennials
What are the three vegetative parts of plants?
Leaves, stems, roots
Two major kinds of leaves are…
Simple and compound
The parts of plants are divided into two major kinds:
Vegetative and reproductive
The three basic patterns of leaf arrangement on a stem are…
Alternate, opposite, and whorled
Five functions of stems:
Stems support/ hold leaves, support flowers and fruit, transports water, gets taller when bud on each stem grows, and stores food.
Two types of stems are…
Aerial stems and subterranean stems
Two major types of root systems?
Tap root and fibrous root
Name and explain the three types of tropism:
a) photosynthesis- response to light
b) geotropism- response to gravity
c) thigmotropism- response to solid objects such as rocks
Plant that has a complete life cycle within one year
Annual
Plant that lives two seasons
Biennial
Plant that lives for more than two growing seasons
Perennial
A leaf whose blade is divided into leaflets on one stem attachment
Compound leaf
One main root that grows downward from the plant
Taproot
Name four types of subterranean stems and give examples.
Tubers (ex: potato)
Bulb (ex: onion)
Corn (ex: garlic)
Rhizome (ex: Johnson grass)
Name three types of stems by woody material in stem. Give examples of each.
Single woody trunks (ex: lumber) Woody stems (ex: tree) Herbaceous stems (ex: corn)
Many small roots that spread out through the soil
Fibrous root
When water moves through a membrane from higher concentrations found in roots
Osmosis
Plant movement
Tropism
Monocot
One leave
Dicot
Two leaves
Has one blade
Simple leave
Has two or more leaflets
Compound leave
Primarily carry out photosynthesis but perform other functions
Leaf function
What does a stem do?
Support leaves and flowers, transport water, and store food
