AP Bio Chapter 24

Epidermal- forms the outer protective covering of a plant. In roots, some epidermal cells have long projections called root hairs, which increase the surface area for water absorption.Ground- fills the interior of a plant. They Contain parenchyma (Found in all the organs of the plants), Collenchyma (Give flexible support to underdeveloped regions of the plant), and Sclerenchyma (Non- living cells that support developed regions of the plant).Vascular- transports water and nutrients in the plant and provides support. Two types: Xylem (Transports water and minerals from the roots to the leaves) and Phloem (transports sucrose and other organic compounds).

Chapter 24: Flowering PlantsSeth and Eric

The stem is the main axis of the plant and has a terminal bud that allows it to elogate to produce leaves.The stem, if it is upright, can expose the leaves to the most sunlight possible.

The leaves carry out the majority of photosynthesis.Size, color, shape, and texture can varry between different plants.Plants that have leaves all year, are called evergreens and plants that loose their leaves are called deciduous.

Root systems are normally underground.The roots anchors the plant into the soil and gives it support.The roots absorb water and minerals from the soil for the plant to use.

Monocots- plants with a seed containing only one cotledon

Eudicots- plants with a seed that contain two cotledon

Tissues

Organization and Diversity of LeavesA leaf contains a thin and flat blade and a petiole connecting the blade to the stem.The body of a leaf is composed of mesophyll tissue.Most eudicot leaves have two regions: palisade mesophyll (Contains elongated cells) and spongy mesophyll (Contains irregular cells connected by air spaces.Three ways a leaf can be arranged on a stem: alternate, opposite, and whorled.

Organization and Diversity of StemsHerbaceous Stems- mature nonwoody stems that exhibit primary growth.Woody Stems- exhibit both primary growth to increase length and secondary growth to increase width.Bark- makes up the length of the tree.Wood- builds up the width of the tree.Stolons- above ground horizontal stems.(Strawberry plant)Rhizomes- underground horizontal stems.

Organization and Diversity of RootsEpidermis- outer layer of the root.Cortex- thin parenchyma cellsEndodermis- boundary between the cortex and the inner vascular cylinder.Vascular Tissue- the pericycle, the first layer of cells in the vascular cylinder.In eudicots the primary root grows straight down forming a taproot.In monocots the roots form a fibrous root system.
