Cells

Difference between plant cell and animal cell

Plant vs Animal

cell wall no cell wall

cell vacuole no permanent cell vacuole

chloroplast no chloroplast

Function of cell wall in plants and bacteria

provides shape and structural support

Protects and gives shape to bacterial cell

Function of cell membrane in plants and bacteria

controls what goes in and out of the cell , selectively permeable

Controls movement of substances

Chloroplast

Helps in photosynthesis

mitochondrion

Helps in aerobic respiration

Nucleus

Carries genetic material and controls cell nutrition

Vacuole

stores sap

Function of Ribosome in plants, animals and bacteria

Helps in protein-synthesis

Amino acids broken down into proteins

Function of Cytoplasm in plants , animals and bacteria

Site for cellular reactions

Contains all cell components

Function of Plasmids in bacteria

Carry extra genetic information

Flagella

They aid in movement

DNA

Contains heroditory information

Describe Eukaryotes

they have a nucleus

Membrane bound organelles, nucleus, mitochondrion and chloroplast

They are plant cells and animal cells

Describe prokaryotes

They lack a nucleus

They also lack membrane bound organelles

What are specialized cells

cells that perform a unique function

Mention the specialized cells and their functions, in animals and plants

ciliated cells -help in movement of mucus in bronchi

nerve cells- conduction of electrical impulses

sperm and egg cell- reproduction

root hair cells- absorption of water and mineral salts

palisade mesophyll cells- photosynthesis

guard cells - open and close stomata

what is a cell?

Cell is the basic unit of life

what is tissue ?

A group of cells with similar structures working together to perform a share function

What is an Organ?

A structure made up of a group of tissue working together to perform a specific function

What is an organ system?

A structure made up of a group of organs with related function working together to perform a body function

What is an organism ?

A living thing that has an organized structure can react to stimuli, reproduce, grow , adapt and maintain homeostasis

Formula for magnification

image size/actual size

1cm is = how many millimeters

10mm

1millimeter is = how many micrometers

1000micrometers

1meter is = how many micrometers

1000000micrometers
