Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
Autotroph is to producer as Hetrotroph is to consumer
Autotrophs make their own food, which makes them producers
While Hetrotrophs cannot make their own food, and must obtain it from another source, making them consumers
Answer:
I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>
Explanation:
I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.
I found rods, and some are gram positive and long. They others are gram negative and very small and short.
The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>
The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
Answer:
A per mineralized piece of wood is known as the "petrified wood."
Explanation:
The petrified wood are available in few parts of the world with variety of colors, which happens as a result of presence trace elements inside the mineral by which the petrified wood is made.It is also believed that they are the remaining of the fossils of terrestrial vegetation. It is made from tree or some tree like plants which have been undergone mineralization process. These woods are much heavier than the normal one.
Answer:
Fungi are unicellular or multicellular eukaryotic organisms that are dependent for their energy and food on dead organic material or other organisms. These organisms produce by both sexual and asexual reproduction.
1. club fungi show a bipolar mating system as they have positive and negative mating strands.
2. sac fungi have an erect fruiting body filled with asci.
3. The chytrids have a cell wall of chitin, a flagellum, absorptive structures for nutrition therefore have a lineage.
4. The common molds grow in the form of hyphae and shows all for of nutrition and live in every possible habitate.
