Stomata

Published on Aug 22, 2017

No Description

PRESENTATION OUTLINE

Stomata

pores in the epidermis allows movement of gases in and out

Transpiration

loss of water from leaves and other organs of the plantin the xylem

Cuticle

permeability barrier for water and other molecules

Epidermis

outer layer of cells covering an organism

Xylem

part of vascular bundle that is responsible for the transports water throughout the plant

Phloem

part of vascular bundle that transports the products of photosynthesis

Guard Cell

pair of curved cells that surround a stoma

Turgor Pressure

pressure of water pushing the plasma membrane against the cell wall

Cohesion

the sticking together of alike molecules

Adhesion

binding of a cell to another cell, or a cell to a surface

Surface Tension

attractive force exerted upon the surface molecules of a liquid by the molecules beneath

Xerophytes

plants that have been adapted to tolerate dry conditions

Halophytes

plants adapted to survive in saline (high salt) conditions.

Source

can be photosynthesising leaves, or storage organs (such as roots) releasing their store of nutrients.

Translocation

organic compounds like sugars + amino acids- are transported in plants from sources to sinks through the phloem.

Meristematic Tissue

Plant tissue consisting of undifferentiated cells

Annuals

a plant that completes its life cycle, from germination to the production of seed, within one year, and then dies.

Biennial

flowering plant that takes two years to complete its biological lifecycle

Perennial

plant that lives for more than two years

Apical Meristems

tip of a plant shoot or root that produces auxin and causes the shoot or root to increase in length

Shoot Apex

terminal bud of a plant, which consists of the apical meristem

Ovary

base of carpel in which the female sex cells develop

Carpel

female reproductive organs of an angiosperm

Pistil

life male reproductive part of a flower

Stamen

male reproductive part of a flower consists of the filament and the anther

Gametophyte

stage in the life cycle of plants and algae that undergo alternation of generations

Sporophyte

multicellular diploid generation found in plants and algae that undergo alternation of generations

Pollination

process by which pollen is transferred to the female reproductive organs of a plant

Fertilization

A process in sexual reproduction that involves the union of male and female gametes each with a single, haploid set of chromosomes) to produce a diploid zygote

Zygote

cell formed by the union of a male sex cell and a female sex cell

Testa

lignified or fibrous protective covering of a seed that develops from the integuments of the ovule after fertilization

Cotyledon

part of the embryo within the seed of a plant

Lateral Meristem

One of the two meristems in vascular plants (the cork cambium and the vascular cambium) in which secondary growth occurs, resulting in increase in stem girth

Angiosperm

Click tA flowering, fruit-bearing plant or tree known for having ovules develop within an enclosed ovary. o add more text here

Monocot

group of flowering plants belonging to the class Liliopsida of Angiospermae, characterized by having only one cotyledon in the seed and an endogenous manner of growth

Dicot

one of the two major types of flowering plants and are characterized by having 2-seed leaves, or cotyledons

Sepal

outer part of the angiosperms

Anther

Pollen-bearing structure in the stamen of the flower usually located on top of the filament of the stamen

Petals

modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators

Filament

stamen of a flower the part that produces pollen consists of a slender stalk, called a filament and an anther

Stigma

pollen-receptive surface of a carpel or group of fused carpels, usually sticky

Style

structure found within the flower. It is a long, slender stalk that connects the stigma and the ovary
