Plant Systems Review #1

Leaves are made up of vascular tissue and ground tissue that use water, sunlight, and carbon dioxide to carry out photosynthesis. What is the level of organization of leaves?

• Organ

• Cell

• Tissue

• Organ System

The xylem of a plant is made up of a group of cells that function together to transport water up from the roots, through the stem, and to the leaves. The xylem is classified as what level of organization?

• Cell

• Tissue

• Organism

A germinating seed means that the seed is sprouting/growing into a plant. The roots grow downward and anchor deep into the ground, while the stems sprout upward above the soil. This is the plant's response to what?

• Osmosis

• Gravity

• Phototropism

• Water

John is at a farmer's market and wants to pick the healthiest, freshest celery. He notices that one batch of celery is wilted and looks "sad." A different batch of celery is rigid and upright so that is the batch he picks. John picked the batch that _____________.

• Has access to more sunlight

• Is in an area of colder temperature

• Has the greatest turgor pressure

• is not for sale

Students placed a plant by a window and watered it everyday. After 1 week, they observed that the plant was growing at a slant towards the window. The students turned the plant so that it was facing away from the window. After another week, they observed that the plant started to grow the opposite direction that it had originally began to grow in. What is this an example of?

• Geotropism-the plants response to gravity

• Photosynthesis- the plant using water and sunlight to grow

• Turgor pressure- the plant growing upright from water pressure pushing up against plant cells

• Phototropism- the plant's response to the stimulus of sunlight

The xylem is plant tissue made up of cells that form a tube up the plant's stem. What is the specific function of the xylem?

• Helps to prevent water loss

• Bring in carbon dioxide to the plant

• Transports water form roots to leaves

• Absorbs sunlight for photosynthesis

The phloem of a plant is vascular tissue that functions to ______________.

• carry glucose up and down the plant for growth

• carry water and minerals from the roots to the leaves

• carry water and minerals from the leaves to the roots

• carry and absorb sunlight and carbon dioxide to other parts of the plant

Which statement is true regarding positive and negative geotropism? Check all that apply.

• Negative geotropism is the plant stem and leaves growing up AGAINST gravity

• Positive geotropism is the plant roots growing down WITH gravity

• There is no such thing as positive and negative geotropism, just geotropism

• Geotropism has to do with sunlight, not gravity

• Geotropism is a plant's response to the stimulus of gravity

Where does turgor pressure apply force to inside a plant seed in order to split it open?

• down

• up

• right

• left

• all of the above
