Plant Tissues Review

What are the two main types of vascular tissues found in flowering plants?

• palisade mesophyll and stomata

• guard cells and stomata

• xylem and phloem

• root cells and palisade mesophyll

Which of the following is true about xylem cells?

• they transport sugars from leaves to other parts of the plant

• they are living cells with flexible cell walls

• they are responsible for performing photosynthesis

• they carry water and nutrients from the roots to other plant parts

How are xylem cells adapted to their function of water transport?

• They contain many amyloplasts

• They are mostly occupied by a large central vacuole

• They are long, narrow, and hollow

• They possess many chloroplasts

How are phloem cells different from xylem cells?

• Phloem cell walls are thicker than xylem cell walls

• phloem cells transport water, while xylem cells transport sugars

• phloem cells are dead, while xylem cells are alive

• Phloem cells have thin walls separating them, and xylem cells have no walls between them

What is the main function of phloem cells in angiosperms?

• providing structural support to the plant

• absorbing water and minerals from the soil

• transporting water and nutrients from the roots to the leaves

• carrying sugars to different parts of the plant

What unique structural adaptation do phloem cells have to facilitate sugar transport?

• They have thicker cell walls for extra support

• They contain chloroplasts to produce sugars

• They form perforated cell walls for quick diffusion

• They have large air spaces to store excess water

Why is it vital for plants to have many tissue types to support photosynthesis?

• different tissue types allow plants to store excess sugars

• each tissue type performs a unique role in maintaining the plant's physical structure

• Only specific tissue types can absorb water and minerals from the soil

• Different tissues give leaf cells access to the reactants of photosynthesis and also process the products

Which plant cell type typically contains the most chloroplasts because of the crucial role it plays in photosynthesis?

• root cells

• phloem cells

• palisade mesophyll cells

• xylem cells

What is the main function of guard cells?

• transport water and nutrients throughout the plant

• store starch for long term energy

• regulate the opening and closing of stomada

• provide structural support to the stem

Amyloplasts are specialized plant cell organelles responsible for

• storing pigments to attract pollinators

• producing ATP energy through cellular respiration

• storing starch as a reserve carbohydrate

• regulating turgor pressure for the opening and closing of stomatas
