Molecular Biology Of The Cell Chapter 17 Part 4

Seeds – a small embryo enclosed in a protective seed coat with nutritive tissue
ATP (adenosine triphosphate) – An adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed. This energy is used to drive endergonic reactions in cells.
Style – The narrow elongated part of the carpel between the ovary and the stigma.
protist – any eukaryote that is not a plant, an animal, or a fungus
Organelle – Specialized structure that performs important cellular functions within a cell
fatty acid – monomers of lipids
Codon – a specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid
The portion of the spinal cord that is known as the “horses tail” is the ____________:
cells-tissues-organs -organ system – 4 levels of organization that combine to form an organism
What is the effect of temperature on photosynthesis? – It is a limiting factor. The rate of photosynthesis goes up as the temperature does, however, this changes when it approached 45degrees, the optimum temperature for photosynthesis. The enzymes controlling it start to be destroyed and the rate of photosynthesis goes back down.
Lysis – a suffix meaning "to break apart."
cerebral cortex – A folded sheet of gray matter forming the surface of the cerebrum. In humans, it contains integrating centers for higher brain functions such as reasoning, speech, language, and imagination.
The pоrtiоn оf the spinаl cord thаt is known аs the “horses tail” is the ____________:
parathyroid hormone (PTH) – A peptide hormone secreted by the parathyroid glands that raises blood calcium level.
Niche – an organisms role and how it interacts with biotic and abiotic factors in the environment
Commensalism – The close association of two or more dissimilar organisms where the association is advantageous to one and doesn't affect the other(s)
farsightedness – An inability to focus on close objects; occurs when the eyeball is shorter than normal and the focal point of the lens is behind the retina. Also called hyperopia.
Cell Membrane – A layer of lipids found near the outside of cells that acts as a barrier between the inside and outside of the cell
