Question

introduction to types of cells
(8) whether an organism is a single - celled microbe or a complex multicellular creature, its existence hinges upon the presence of cells. from the unicellular amoeba to the blue whale, every living thing is composed of one or up to trillions of cells.
(9) there are two types of cells: prokaryotic cells and eukaryotic cells. eukaryotes (organisms that are made up of eukaryotic cells) can be multicellular or unicellular and make up animals, plants, protists, and fungi. bacteria and archaea contain prokaryotic cells and are always unicellular, or single - celled, organisms.
(10) all cells contain organelles. cell organelles are specialized structures within cells that perform distinct functions, contributing to the overall survival, growth, and function of the cell. each organelle plays a specific role and collectively they enable cells to carry out a wide range of tasks necessary for life.
(11) while the specific organelles present in cells can vary depending on the type of cell and whether its a prokaryotic or eukaryotic cell, there are a few organelles that are commonly found in most types of cells. these organelles contribute to essential cellular functions and are considered fundamental components of all biology. below are types of organelles that are found in all cells:
cell membrane: the cell membrane is a lipid bilayer that separates the cells internal environment from the external environment. it controls the passage of substances in and out of the cell and plays a role in cell communication and recognition.
cytoplasm: the cytoplasm refers to the fluid - filled interior of the cell that surrounds the organelles. it contains molecules, ions, and cellular structures.
ribosomes: ribosomes are structures responsible for protein synthesis. they are found freely floating in the cytoplasm or attached to the endoplasmic reticulum.
genetic material: all cells contain genetic material, either in the form of dna or rna which carries the instructions for growth, development, and functioning. genetic material is passed down from parents to offspring.

Explanation:

Based on the information in the text:

• Prokaryotic cells are always unicellular, make up bacteria and archaea.
• Eukaryotic cells may be unicellular or multicellular and make up plants, animals, fungi, and protists.
• Both prokaryotic and eukaryotic cells have a cell membrane, contain organelles, and have genetic material. The cell membrane controls substance passage and cell - cell communication, the cytoplasm holds cellular components, ribosomes are for protein synthesis, and genetic material carries growth and function instructions.

Answer:

1. P

6. B
7. Cell Membrane; Controls passage of substances, cell communication and recognition
8. Cytoplasm; Holds molecules, ions and cellular structures
9. Ribosomes; Protein synthesis
10. Genetic Material; Carries instructions for growth, development and functioning
