Interactive Cell

Question 1

Nucleus

Answer 1

Provides cell with DNA, communicates with cytosol via nuclear pores

Question 2

Nucleolus

Answer 2

The prominent structure IN the nucleus, makes ribosomes and are then transferred to the rough ER for protein synthesis

Question 3

Cytosol

Answer 3

Mostly water, all the other organelles reside within it, full of protein that controls the cell metabolism

Question 4

Cytoplasm

Answer 4

The cytosol and the organelles in the cytosol

Question 5

Centrosome

Answer 5

Divided into two and each has a pair of small organelles called centrioles, moves to opposite ends of the cell

Question 6

Centriole

Answer 6

A ring of nine groups of fused microtubules, 3 per group, part of the cytoskeleton

Question 7

Golgi Apparatus

Answer 7

A membrane bound structured with a singular membrane stacked up, has lysosomes, peroxisomes, and secretory vesicles

Question 8

Lysosomes

Answer 8

Released into the vacuole near the bacteria to kill it

Question 9

Peroxisomes

Answer 9

Protects the cell from its own toxic hydrogen peroxide, breaks it down into water and oxygen

Question 10

Secretory Vesicles

Answer 10

Hormones, neurotransmitters, etc, are moved up to the surface of the golgi for release

Question 11

Cell Membrane

Answer 11

Double layer of phospholipids, controls the entry and exit of ions, the top and bottom part of a cell membrane are hydrophilic while the middle is hydrophobic

Question 12

Mitochondria

Answer 12

The powerhouse of the cell, has a double membrane

Question 13

Vacuoles

Answer 13

In animal cells, they are small and are responsible for intracellular digestion and cellular waste
In plant cells, they are often large and store nutrients and waste products

Question 14

Cell Wall

Answer 14

Made up of polysaccharides, serves as a protective barrier

Question 15

Chloroplast

Answer 15

Contains chlorophyll responsible for the green plant color and ability to absorb sunlight, has a double outer layer

Question 16

Smooth Endoplasmic Reticulum

Answer 16

Appears smooth, performs the tasks including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins, control of calcium release in muscle cell contraction

Question 17

Rough ER

Answer 17

Appears pebbled, has numerous ribosomes attached to it, proteins are synthesized here and are transported through the cell

Question 18

Ribosomes

Answer 18

Packets of RNA and proteins, has a large and small subunit

Question 19

Cytoskeleton

Answer 19

Helps remains cell shape, is an organized network of three primary protein filaments [microtubules, actin filaments (microfilaments), intermediate fibers], is important for the cell’s ability to move
