Cell Structure And Function

Front 1

Cells.

Back 1

Basic structural and functional units of every organism.

Front 2

Types of Cells

Back 2

Prokaryotic cells

Eukaryotic cells

Front 3

Prokaryotic cells

Back 3

DNA is concentrated in a region called the nucleoid.

DNA is in direct contact with rest of cell contents.

As many of its organelles are not membrane bound.

Don't have a nucleus.

Front 4

Eukaryotic cells

Back 4

Their DNA is found it a structure that is membrane bound.

Eukaryotic cells have a nucleus.

Front 5

Membranous Organelles

Back 5

1. ER

2. Lysosomes

3.Mitochondria

4. Golgi Apparatus

5.Micro bodies

6.Nucleus

Front 6

Nucleus

Back 6

Genetic centre of all eukaryotic cells.

Front 7

Theory On Cells.

Back 7

All life comes from cells and all cells come from other cells.

Front 8

DNA

Back 8

Directs all cell activities.

Front 9

Cytoskeleton

Back 9

Provides structural support of the whole cell.

Front 10

Parts of the cytoskeleton

Back 10

Microfilament.

Microtubules.

Intermediate filament.

Front 11

Golgi Apparatus

Back 11

One end of the Apparatus acts as the receiving dock(the cis dock) while the other,the shipping dock(the trans dock).

Front 12

Lysosomes

Back 12

Are major digestive compartments.

They contain enzymes that work best in acidic environments and are capable of hydrolizing bacteria.

Front 13

The vacuole

Back 13

Derived from both the golgi Apparatus and ER, acts as a food storage,solute transport,and removal of excess water organelle.

Front 14

Pexosomes

Back 14

Contain enzymes that remove hydrogen atoms from various substrates and transfer them to oxygen to produce hydrogen peroxide as a by product.

Front 15

Mitochondrion

Back 15

Major organelle in cellular respiration hence ATP production.

It also has it's own DNA and Ribosomes.

Front 16

Chloroplasts

Back 16

Capture solar energy and convert it into chemical energy in form of ATP and NADPH. For the process of Photosynthesis.

Hint 16

Energy conversion

Front 17

Compartments of chloroplasts

Back 17

Intermembrane

Stoma enclosed by inner membrane

Space inbetweeners membranous tubules.

Front 18

Cell membrane/plasma membrane

Back 18

Fluid filled mosaic that is made up if phospholipids and proteins.

Front 19

Cell Membrane

Back 19

Has selective permeability.

Front 20

Types of traffic across plasma membrane

Back 20

Passive and Active Transport

Front 21

Passive Transport

Back 21

Does not require any energy for substances to cross membrane.

Down

Front 22

Active Transport

Back 22

Uses energy to move solute against their concentration gradient.

Uphill

Front 23

Osmosis

Back 23

Movement of water molecules from hypotonic solution to hypertonic solution.

Front 24

Components of a nucleus.

Back 24

Chromosomes

Nuclear Membrane(nuclear envelope)

Nucleolus

Nucleoplasm

Front 25

Components of a prokaryotic cell.

Back 25

Bacterial chromosome

Nucleoid

Fragella

Plasma membrane

Cell wall

Ribosomes

Fimbriac

Front 26

Cytosol

Back 26

Semi fluid,jellylike substances in which subcellular components are suspended.

Front 27

Ribosomes

Back 27

Tiny complexes that make proteins according to instructions from genes.

Front 28

Ribosomes

Back 28

Made out of proteins and RNA

Front 29

Types of RNA

Back 29

mRNA

rRNA

Front 30

Types of RNA

Back 30

mRNA

rRNA

Front 31

RNA

Back 31

Is obtained from the nucleolus at the point where ribosomes are arranged in a cell.

Front 32

Ribosomes

Back 32

Assume the role of bringing together amino acids to form particular proteins which are important for completing the cell activities.
