What is the difference between Animal, Plant and Fungal cells?

Animal Cells

Animal Cells don’t have a cell wall.

Animal cells don’t make their own food, they gain nutrients from things we eat.

Animal Cells have the same organelles as fungal cells.

Plant Cells

Plant cells make their own food using photosynthesis and the sun.

Plant cells have a cell wall.

Plant cells have more parts than animal cells.

Fungal Cells

Fungal Cells have the same organelles as animal cells.

Fungal Cells have a cell wall like plant cells.

Fungal cells do not have chloroplasts, which make photosynthesis, they get food from whatever they are growing on.Slide3

Organelles

Nucleus (control Centre of the cell)

Nucleolus (found inside the Nucleus, is involved in protein synthesis)

Cell wall (Plant and Fungi only) (helps keep the cells rigid)

Cell Membrane (protects the cell)

Chloroplasts (Plants Only) (where photosynthesis is made using energy from the sun)

Endoplasmic Reticulum (smooth and rough) (helps things travel)

Vacuole (stores water, waste and food)

Chromosomes (genetic material found in the nucleus)

Lysosome’s

(like a garbage removal unit that gets rid of unwanted matter from the cell)

Mitochondria (where the energy for the cell is made)

Golgi Apparatus (packages protein)

Ribosome's (create proteins for growth and repair of the cell)Slide4

How do cells reproduce?

There are 5 phases to the asexual of a cell. This is called Mitosis, They are

Interphase

, Prophase, Metaphase, Anaphase,

Telophase

. When a cells reproduces asexually, they do so without intercourse. The cell makes a copy of itself. Some cells split themselves in two to do this. The result is a daughter cell. The daughter cell is identical to the parent.

Not all cells reproduce in the same way. Some reproduce sexually and others, asexually.

Other cells reproduce sexually. This is called

Meiosis.The

process is different when reproduction is done sexually. There is a female cells and a male cell. The cells of higher plants or animals have two sets of chromosomes (they are called diploids). When gametes or sex cells are produced they only have on set of chromosomes (they are called haploids). During fertilisation, two cells merge into one and therefore restores the diploid state.

The process of asexually reproduction.Slide5

Fungi Cells

Adjective:

Any of a diverse group of eukaryotic single celled or multinucleate organisms 

that live by decomposing and absorbing the organic material in which  they grow, comprising the mushrooms, moulds, mildews, smuts, rusts, and yeasts,

 and classified in the kingdom Fungi or, in some classification systems, 

In the division Fungi  (Thallophyta) of the kingdom Plantae.Slide10

Other Parts/Types of the CellSlide14

Conducting Cell

Conducting cells are long tubes like pipes

.

Conducting cells transport water from where it is collected in the roots of the plant to where it is needed in the leaves so photosynthesis can take place. Slide15

Guard Cell

Guard cells work in pairs, opening and closing like little pores. Gases which are needed for the plant enter through these Guard cells and unwanted gases exit through the Guard cells. Slide16

Chloroplasts– Photosynthesis

Chloroplasts are found on near the surface of green leaves and stems of plant. Chloroplasts trap the suns energy and turn it into food for the plant. This process is called photosynthesis. Slide17

Unicellular Organisms

Definition –

Adjective:

Having or consisting of one single cellSlide18

Paramecium

Paramecium can move, eat and reproduce. Paramecium live in water filled environments, usually warm, stagnant water. They are capable of both sexually and asexual reproduction. Slide19

Euglena have chloroplasts and use photosynthesis but they can also absorb food from their environment. Scientist have been debating for years weather they are a plant or an animal cell, so right now they are neither. They are classified as

Protists

. They usually live in quiet ponds or puddles. Slide20
