The main photosynthetic area of a leaf is

What tissue is found within a leaf vein?

Match the following modified stems with their descriptions. a.bulbs b.tubers c.cladodes d.rhizomes e.stolons -fleshy stems that grow underground; they have nodes from which new stems sprout

Approximately how many species of flowering plants are known?

Match the following descriptions with a.Eudicots b.Monocots c.both monocots and eudicots d.neither monocots or eudicots -vascular bundles organized in a ring in the stem

Root nodules found on the roots of leguminous plants are involved in supplying which element for the plant?

Choose the one most appropriate answer for each. a.gives rise to periderm b.phloem cells that help load the phloem pipelines c.dead cells with perforation plates; more efficient at water conduction than other xylem cells d.cells that conduct food from photosynthetic source area to storage sink area e.a cylinder of vascular tissue sheathed by parenchyma cells f.clusters of strands containing xylem and phloem g.dead cells without perforation plates; conducting cells of xylem h.cells with thick secondary walls impregnated with lignin that are especially abundant in fruits and seeds i.the principal photosynthetic region of a leaf j.regions that can undergo mitosis k.gas exchange and storage plus photosynthesis -tracheids

Match the following descriptions with a.transpiration b.translocation c.both transpiration and translocation d.neither transpiration or translocation -osmosis plays a major role in this process

In which of the following plants would you NOT find a division of the leaf into distinct layers?

Choose the one most appropriate answer for each. a.outer tissue that is part of the dermal system b.leaf's photosynthetic tissues (palisade and spongy)are in this category c.transports photosynthetic products away from leaves and stem d.cell divisions here produce secondary xylem and phloem e.transports water and dissolved nutrients up to the stem and leaves f.replaces the epidermis in plants that undergo secondary growth g.responsible for all primary growth h.regulates the movement of carbon dioxide into the leaf and movement of water out of the leaf i.generally,dead cells that provide support and strength to all three tissue systems j.ground tissue centrally located inside a ring of vascular bundles -apical meristem

Roots are involved in all EXCEPT which of the following activities?
