Why was an algae cell included along with the plant and animal cells? Use complete sentences.
erik [133]

Answer:

Explanation:

As plants because they are autotrophic in their mode of nutrition.,They have photosynthetic organelle which can be used to synthesise their food by themselves.Thus they contain  membrane bound chloroplast,the photosynthetic organelle peculiar to plants .They also contain mitochondria and nucleus which  are all present in green plants.

In addition some algae undergo asexual reproduction which is peculiar to green plants.They are different due to lack of complexity of tissues e.g xylem,phloem present in plants etc.

They are similar to animals because they contain membrane bound organelles of  mitochondrial,nucleus .These are the characteristic feature of Eukaryotas They are also capable of sexual reproduction ,and locomotion with the aid of flagella.(Chlamydomonas)

What is the function of the following organelles?
MrRa [10]

Answer:

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.

The plasma membrane is the same as a cell membrane

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

Number the following steps for the reproductive system of a self pollinating flowering plant in order from 1 to 5. Use the parts
Leviafan [203]

Answer:

3 Pollen tube forms and grows through the style

5 Sperm fertilizes the egg

1 Pollen is released from the anther

4 The pollen tube reaches the ovule within the ovary

2 Pollen sticks to the stigma

Explanation:

The process of double fertilization entails the fertilization of the egg by one sperm and that of two polar nuclei to produce the triploid endosperm tissue that nourishes embryo.

* The image describes the process in detail.
