Ch.4 Biology Notes
Which carrot strip became stiff
B. The carrot placed in freshwater
Nucleus
The "brain" or control center of a cell; houses the DNA heredity material.
Mitochondrion
The "powerhouse" of the cell; creates energy for the cell.
Lysosome
The "suicide sac" and has digestive enzymes.
Chloroplast
Stores energy from sunlight usually as glucose; photosynthesis.
Vesicle/Vacuole
Stores water, food and wastes.
What type of solution is cell A placed?
isotonic
What type of solution is cell B placed?
isotonic
Eukaryotic
large, complex cells that have a true nucleus and organelles.
Flagella
long, hair-like structures used for locomotion and movement in some cells.
What process has happened to the red blood cell
lysis
Ribosomes
"Protein factories" that synthesize or make proteins for a cell.
Smooth endoplasmic reticulum
A tunnel-like passageway for lipids and toxic chemicals; does not have ribosomes attached.
Prokaryotic
small, very simple cells without a nucleus; a nucleiod area houses the DNA.
Rough endoplasmic reticulum
A passageway or flattened tunnel to transport proteins; has ribosomes.
What process is occurring here?
Diffusion
Golgi apparatus
Flattened sacs that change/modify a substance, package it, and ship it out of the cell or to another region of a cell
Central Vacuole
Large storage for water, food, color pigments, enzymes and wastes.
Nucleolus
Makes the subunits of ribosomes; inside the nucleus.
Plasma membrane
The double layered membrane that separates the "living" cytoplasmic material from the nonliving material outside of a cell.
Nuclear envelope
The double layered membrane that separates the nuclear material fromthe cytoplasm.
Cytoskeleton
The framework and support structures found in the cytosol.
Cell wall
The outer boundary of a plant cell that gives it shape, support, and structure.
Cytoplasm
The semi-solid where all metabolism and chemistry takes place.
What type of solution is cell A placed?
hypertonic
What type of solution is cell C placed?
hypertonic
Which solution was the "limpy" carrot placed in?
hypertonic
What type of solution is cell B placed?
hypotonic
What type of solution is cell C placed?
hypotonic
Cilia
numerous short, fine hairs on the surface of some cells; beat in unison like "boat oars".
