Review for Unit 4 test You can do it!!!!

Without gas exchange, a plant would be unable to make food make minerals absorb sunlight absorb water from the soil.

Xylem and phloem are NOT transport subsystems present in bryophytes vascular tissues present in ferns.

Which of the following is NOT a characteristic of all plants? are eukaryotic produce seeds have cell walls are multicellular

Plants use the energy of sunlight to exchange gases with the atmosphere carry out cellular respiration take in water from the soil carry out photosynthesis.

Which of the following includes all the others? Xylem Phloem vascular tissue tracheids

Which term below is LEAST closely related to the others? Fruit Ovary seed cone

pollen grain Seed Spore gametophyte Which of the following includes a plant embryo, a food supply, and a protective covering? pollen grain Seed Spore gametophyte

Living on land required that plants evolve photosynthetic pigments conserve water exchange gases have cell walls.

conduct sugars to the roots absorb carbon dioxide from the air If some of the xylem of a young oak tree was destroyed, it would most likely interfere with the tree’s ability to conduct sugars to the roots absorb carbon dioxide from the air absorb sunlight conduct water to the leaves.

A monocot is an angiosperm that has a taproot one seed leaf branched veins two seed leaves.

Ground tissue is found in plant stems only roots and stems only stems and leaves only roots, stems, and leaves.

Angiosperms produce seeds inside protective structures called pollen grains Ovaries Cones petals.

Root pressure causes a plant’s roots to absorb water. forces the water in xylem downward. is produced in the cortex of the root. is produced in the vascular cylinder by active transport.

phloem from the leaf of a plant Which of the following should a student examine under a compound microscope to observe cell division? epidermis of a leaf xylem from a tree trunk tip of a shoot phloem from the leaf of a plant

The vascular cylinder of a root consists of xylem only. phloem only. xylem and phloem. xylem, phloem, and ground tissue.

meristematic tissue ground tissue phloemd xylem Which of the following is the only tissue that produces new plant cells? meristematic tissue ground tissue phloemd xylem

Most of the photosynthetic activity in plants takes place in the mesophyll. guard cells. stomata. xylem.

adhesion only. pressure. capillary action. cohesion only. Water will move higher in a narrow glass tube than in a wide glass tube because of adhesion only. pressure. capillary action. cohesion only.

The stomata of leaves are usually open in light if a plant has enough water. light if a plant has too little water. darkness if a plant has enough water. darkness if a plant has too little water.

Vascular tissue in plants consists of meristem. parenchyma and collenchyma cells. xylem and phloem. epidermal cells.

A seed plant is anchored in the ground by its stems. leaves. roots. trichomes.

Through which plant cells does water move by capillary action? phloem cells mesophyll cells guard cells xylem cells

taproot. monocot. fibrous root. extensive root system. A carrot is a(an) taproot. monocot. fibrous root. extensive root system.

Minerals from the soil move into roots by diffusion. active transport. transpiration. root pressure.

One of the main functions of stems is to carry out photosynthesis. transport substances between roots and leaves. store carbohydrates. store water.

The attraction of water molecules to other molecules is called adhesion. capillary action. cohesion. transpiration pull.

The sterile leaves of a flower are the carpel and stamens. stigma and style. filaments and anthers. sepals and petals.

Alternation germination. pollination. competition. A seed that is dispersed to an area far away from the parent plant might face less Alternation germination. pollination. competition.

Seeds dispersed by animals typically are contained in fleshy, nutritious fruits. buoyant structures. cones. lightweight structures.

Corn, sugar beets, cauliflower, and cabbage were all developed by plant propagation. pollination. germination. selective breeding.

Pollen grains are produced by male reproductive structures. ovules. female reproductive structures. flowers.

Most people in the world depend on food crops such as sugar beets, cabbage, and broccoli. strawberries, chilies, and avocadoes. wheat, rice, and corn. apples, grapes, and strawberries.

A ripened ovary that contains seeds is called a(an) embryo. fruit. ovule. vegetable.

The seed type shown in Figure 24-5 that is generally dispersed by animals is(are)

The early growth stage of a plant embryo is called fertilization. germination. dormancy. pollination.

Seeds that are dispersed by wind and water typically are lightweight. nutritious. large. sweet and fleshy.
