7th grade Science//POINTS AND BRAINLIEST...AND plz hurry... Function of Organelles- Give the functions of the listed organelles:
vova2212 [387]

Answer: Chloroplast - The organelles are only found in plant cells and some protists such as algae. ... Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.

Mitochondria - are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.

The cell membrane- controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

Cytoplasm - is present within the cell membrane of all cell types and contains all organelles and cell parts. Cytoplasm has various functions in the cell. ... Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place.

Nucleus - This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.

Ribosomes - are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum. ... Proteins are an essential part of all cells.

Endoplasmic reticulum (ER) - in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .

Vacuoles - are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.

Lysosome - Inside a cell, numerous organelles function to remove wastes. One of the key organelles involved in digestion and waste removal is the lysosome. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.

Chromosomes - are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA) Chromosomes are important to this process to ensure the DNA is accurately replicated.

The nucleolus - makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell.

Vesicles - are small cellular containers that perform a variety of functions. They can be used to move molecules, secrete substances, digest materials, or regulate the pressure in the cell.

The cell wall - is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.

Which phrase best describes the bond in H2?
Gala2k [10]

Answer and Explanation:

Two hydrogen atoms, each containing one electron, approach each other in the formation of a molecule of hydrogen. Each atom needs a total of two electrons to fill their outermost energy level and make them stable. The best choice is to share their single electrons. Hence, a pair of bonding electrons is shared between the hydrogen atoms in the molecules.

This constitutes a single covalent bond. Hence, the correct option is B)
