Bacteria and Fungi

Adapted from Mr HaywardY11 Science

 

MICROBES MOROITI ∙ ∙จลชพ Micro-organisms or microbes are microscopic living things including: Bacteria (แบคทเรย) Fungi (หหน) Viruses (ไวรส) Algae (สาหราย) Protozoa (โปรโตซว)

All fungi grow best in warm (อนๆ), moist (ฉำ�า) conditions. For example, bread is more likely to go mouldy in summer than in winter, especially if the humidity is high or it is left in a plastic bag.

FUNGI KŌPURA WHETŪ ∙ ∙ เชอรา

Fungi can be single-cellular (e.g. yeasts - ยสต) or multicellular (e.g. mushrooms). Unlike other microbes, some fungi are visible to the naked eye.

The body of a multicellular fungi is made up of fine thread like structures called hyphae (singular hypha - ใยรา). Many hyphae are matted together to form a structure called mycelium (ไมซเลยม).

Fungi grow reproductive structures called sporangia (singular sporangium - อบสปอร)

STRUCTURE OF FUNGI ∙โครงสราง

Spores - อบสปอร Tiny particles containing genetic material in a tough outer coat.

Mycelium A tangled web or mat of hyphae.

Sporangium A fruiting body containing spores.

Hyphae Fine threads that spread through the surface layer of a food source.

FlagellaAllow the cell to move

Cell wall - ผนงเซลลGives shape and protects the membrane

Nuclear regionContains the genetic code (รหสพนธกรรม)

Cell/Plasma membraneControls the movement of substances into or out of the cell

CytoplasmWhere life functions are carried out

Gelatinous sheath – กลายเปนกาว + ปลอก Protects from viruses

CiliaAllow the cell to move

STRUCTURE OF BACTERIA

Controls entry and exit of dissolved substances.

Sticky layer that protects cell from viruses.

Where the chromosomes are located.

Provides shape and protection.

Where life functions take place.

Allow the particle to move.
