Flowering plants as functioning organsims Flashcards
Respiration
A process which in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Sexual Reproduction
The production of new living organisms by combining genetic information from two individuals of different types (sexes).
Osmosis
A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated one, thus equalising the concentrations on each side of membrane.
Root hair cells
Each of a large number of elongated microscopic outgrowths from the outer layer of cells in a root, absorbing moisture and nutrients from the soil
Cells
The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane
Xylem Tissue
Xylem tissue is the water transporter cells of plants. It carried water around s plant. The presence of vessels is s characteristic feature of flowering plants.
Transpiration
The act of plants giving off water vapour through the stomata.
Chlorophyll
A green pigment, present in all green plants and in Cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
Stomata
Any of the minute pores in the epidermis of the leaf or stem of a plant, forming a silt of variable width that allows movement of gases in and out of the intercellular spaces.
Phloem cells
A tissue in vascular plants that conducts food from the leaves and other photosynthetic tissues to other plant parts
Stem cells
Cells that have the ability to divide and become specialised cell.
Mitosis
A type of cell division where one parent cell divides to produce two daughter cells with identical genetic instructions carried in their DNA.
Chromosomes
When the cell divides the modules condense into structures called chromosomes which are visible under the light microscope
Vegetative reproduction
Is the process when your plants arise without the production of seeds. In plants asexual reproduction is generally referred to as vegetative reproduction. It occurs in specialised cells tissues roots, stem and leaf of some flowering plants
Budding
A single bud of the desired plant is inserted into a dolt in the bark of a compatible root stock. Disease resistant root stocks can be used to improve plant health in the new plant
This is one plant cloning technique
