Answer 1

Structures found in the cytoplasm made of microtubules that produce the spindle fibers during mitosis.

Question 2

what are chloroplasts?

Answer 2

Organelles found in plants and algae that are the site of photosynthesis.

Question 3

what are cilia?

Answer 3

Small hair-like structures that project from the surface of cells.

Question 4

what is confocal microscopy?

Answer 4

A type of microscopy that uses lasers to scan a specimen point by point to produce an image.

Question 5

what is the cytoskeleton?

Answer 5

a mesh of protein fibers found in eukaryotic cells used for structural support and intracellular transport

Question 6

what technique is used to differentiate between parts of a specimen?

Answer 6

staining

eukaryotic cell OCR definition

Answer 7

a type of cell that contains a nucleus, along with membrane bound organelles

Question 8

what is a flagella?

Answer 8

a whip like structure found on bacterial cells for cell movement

Question 9

what is the Golgi apparatus

Answer 9

An organelle found in eukaryotic cells that is involved in the modification
and packaging of proteins.

Question 10

what is a light microscope?

Answer 10

a type of microscope that uses visible light and a range of magnification lenses to show the light reflecting of a specimen

Question 11

what are lysosomes?

Answer 11

membrane bound proteins found in the cytoplasm that contain a hydrolytic enzyme called lysozyme

Question 12

magnification

Answer 12

image size ÷ real size

Question 13

what is mitochondrion?

Answer 13

organelle found in eukaryotic cells that is the site of respiration

Question 14

what is the nuclear envelope?

Answer 14

a double membrane that surrounds the nucleus

Question 15

what is the nucleolus?

Answer 15

a structure that is found inside the nucleus that contains proteins and RNA is involved in synthesizing proteins

Question 16

what is the nucleus?

Answer 16

an organelle found in eukaryotic cells that stores the genetic info of the cells (as chromosomes). surrounded by the nuclear envelope

Question 17

what is the plasma membrane?

Answer 17

barrier formed of phosphate heads and tails forming a wall due to hydrophilic and d hydrophobic nature (respectively).
semi permeable lipid bilayer studded with proteins that surround the cell and many organelles

Question 18

what are prokaryotic cells?

Answer 18

a type of cell that does not contain any membrane bound organelles or a nucleus

Question 19

what is resolution?

Answer 19

the ability to distinguish two points on a specimen

Question 20

what are ribosomes?

Answer 20

organelles that are found either free in the cytoplasm or bound to the rough endoplasmic reticulum

Question 21

what is the rough endoplasmic reticulum?

Answer 21

membrane bound organelle involved in the synthesis of proteins, covered in ribosomes

Question 22

what is an electron scanning microscope?

Answer 22

a type of microscope that passes a beam of electrons over the surface to produce a (3D) image

Question 23

what is a smooth endoplasmic reticulum?

Answer 23

a membrane bound organelle involved in lipid synthesis

Question 24

what is a transmission electron microscope?

Answer 24

A type of microscope that passes a beam of electrons through a sample to produce an image.
