Cell structure 🧫 Flashcards
Type of Animal cell with no mitochondria
Red blood cell
Name and location of the stage of aerobic respiration that does not occur in the mitochondria
Glycolysis,
Cytosol
Name of chemical reaction, involving Acetyl Co.A which does not occur in the mitochondrion
Krebs cycle
Number of carbon molecules in acetyl Co.A
2
Describe condition where lactic acid is produced during respiration
Oxygen deficiency
Distinguish between eukaryotic and prokaryotic cells
Eukaryotic cells have membrane enclosed organelles and a nucleus.
Prokaryotic cells have no membrane enclosed organelles and no nucleus
Stain used to examine cells under microscope
Iodine or methylene blue
Benefit of using stain to examine cells with microscope
Makes cells more visible
Define term tissue
Group of cells working together to carry on the same function
Two types of animal tissue
Muscle,
Connective
How is connective tissue adapted to carry out its function
Strong yet flexible
How is muscle tissue adapted to carry out its function
Contract and relax
Define Tissue culture
Growth of cells, in vitro, on a sterile nutrient medium
Three applications of tissue culture
Micropropagation,
Skin grafts,
IVF
Three processes where molecules can move through cell membranes
Osmosis, diffusion, active transport
Why organelles involved in aerobic respiration is found in different amounts in different cells
Cells need different amount of energy
Organelle that has genetic material
Mitochondrion
Function of named tissue in plants
Vascular tissue,
Transports minerals and water to different parts of the plant
Xylem:
Phloem:
Function of named tissue in animals
Muscle tissue,
Contracts and and relaxes
Two requirements for successful tissue culture
Nutrients, suitable temperatures
One way vascular tissue is adapted to carry out its function
Has xylem and phloem
How you obtained sample of cells in experiment
Rubbed inside cheek with swab
How coverslip is used
Coverslip lowered at a 45 degree angle
Why coverslip is used
To protect sample from drying out
Location of cell membrane in plant cells
Immediately inside cell wall
Selectively permeable
Only some us are allowed through
Structure by which amoeba gets rid of excess water that has entered by osmosis
Contractile vacuole
Name a molecule and give a precise location at which it diffuses in the human body
What are the walls of xylem vessels reinforced with
Lignin
Explain biological basis for the use of high sugar or high salt concentrations in the preservation of food
Bacteria loose water by osmosis
Function of ribosome
Protein synthesis,
Makes proteins
Function of cell membrane
Selectively permeable
