What are Bacteria?
Bacteria are single celled microbes that are very hard to see with the naked eye. The cell structure is m much simpler than other organism for that it has no nucleus or membrane. Bacteria are also known for being the smallest life organisms around. There are 2 types of bacteria. 1 is Archbacteria. 2. Eubacteria.
Protists are organisms in the kingdom Protista. The organisms are eukaryotes which means they are made up of single or multiple cells which all contain a nucleus and a membrane. protists are a cool group of eukaryotes that cannot be classified as animals, plants, or fungi. Organisms in the Protista kingdom include amoebae, euglena and slime molds.
Protist move throuout the slime molds and other things and reproduce with bacteria and fungi. Three types of fungus like protists
cellular slime molds
acellular slime molds
Fungi are a group of organisms that were once considered a part of the plant kingdom. Now some scientists think that fungi are neither plants or animals. They grow on logs of wood and dead plants. They have no flowers, stem, root and they cannot make their own food. They feed on dead plants and animals and decompose them. Moulds, mushrooms and yeast are all fungi!
Fungi have spores that can grow like seeds into new plants. If you see a mold growing on bread under a microscope you will find that each stalk has a swollen head. This is called the spore bag which bursts open when spores are ripe in wich they scatter them. They are caused by wind, animals, etc., and give rise to new fungi. In mushrooms, the spores are located under the cap.
Humans use fungi as food for delicious things such as. Mushrooms and truffles. We also use this for yeast, and cheese molds
What makes a plant a plant
Well all plants do share these characteristics:
* Plants make food: That’s right photosynthesis. Green chlorophyll absorbs energy from the sun. the plants inhale carbon dioxide. Then exhale oxygen we can breathe. They also make sugar. * Plants have cell walls: a plant cell is surrounded by a rigid cell wall. It helps support and protect the plant. * Plants have a cuticle: A waxy layer that coats the surface of stems, leaves, and other plant parts exposed to the air. Also keeps plants from drying out. * Plants reproduce: With spores.
Examples of non vascular plants and vascular plants are.
Non vascular plants are mosses, liverworts, and hornworts
vascular ferns are, flowering plants, club mosses, gymnosperm, and conifers
Plants are very important to us because they provide us with sugar which is used in a lot of daily foods and they also give out oxygen that keeps us alive and breathing.
How do non seed plants reproduce? Well they actually poop out spores that spread to other plants and reproduce with what they land on.
Conifers are non-flowering plants, like a pine cone. Another name for them is called a gymnosperm, which is like a naked seed. They reproduce by the pine cone going through meiosis which creates a egg type thing inside of the conifer which creates a new pine cone. They carry out pollen from them when they open.
How do flowering plants reproduce?
The first thing they do is Pollinate then they disperse seeds Flowering plants reproduce through the process called pollination. There are different types of pollination: * Animal pollination
* Insect pollination
* Wind pollination
How do plants help plants reproduce well that’s easy?
They help by planting seeds when eaten by birds or humans because the seeds they contain will grow just...
