Nucleus & Genetic Material
This organelle stores a cell’s DNA and controls its activities.
Circular
Name 3 body system
?
Hollow rods that move materials, separate chromosomes, and support cell shape.
Microtubules
Animal-cell junctions that create a seal to prevent fluid leakage
Tight Junction
DNA plus proteins, found in the nucleus when a cell is not dividing, is called this.
chromatin
This organelle is the site of cellular respiration and ATP production.
Mitchondria
A network of membranes with rough and smooth regions involved in synthesis and transport.
ER
Thin filaments used in muscle contraction, cell motility, and tension resistance.
Microfilaments
Small channels that connect plant cells, allowing cytoplasm to flow.
Plasmodesmata
This dense structure inside the nucleus produces rRNA and assembles ribosome parts.
Nucleolus
Plant cells use this organelle to capture sunlight and make sugars.
Chloropast
This organelle modifies, sorts, and ships products from the ER.
A whip-like cellular appendage specialized for locomotion.
Flagellum
A rigid layer surrounding the plasma membrane in plants.
Cell Wall
The double membrane surrounding the nucleus, perforated with pores, is called this.
Nuclear envelope
This organelle transfers hydrogen to oxygen, forming and breaking down hydrogen peroxide.
Peroxisome
A membrane-enclosed sac full of hydrolytic enzymes used for intracellular digestion.
Lysosomes
Together, microtubules, microfilaments, and intermediate filaments form this internal support system.
Cytoskeleton
Channels linking animal cells’ cytoplasm for communication.
Gap Junctions
Tiny openings in the nuclear envelope allow RNA and proteins to pass in and out. What are they called?
Nuclear pores
Carbohydrate metabolism and detox of drugs occur in this part of the ER.
Smooth ER
This selectively permeable barrier surrounds all cells.
Plasma Membrane
Organizing centers for microtubules in animal cells, often paired, are called these.
Centrioles
Junctions that anchor animal cells together like rivets.
What are desmosomes?
