passive transport does not mean that a particle is inactive or not moving it means the particle can move without requiring what

Answer 1

Passive transport does not mean that a particle is inactive or not moving; rather, it means that the particle can move across a membrane without requiring energy input from the cell. This movement occurs along a concentration gradient, meaning particles move from an area of higher concentration to an area of lower concentration, thus utilizing the natural kinetic energy of the particles. Examples of passive transport mechanisms include simple diffusion, facilitated diffusion, and osmosis.

Answer 7

Sure! Here are one-sentence descriptions of the form and function for each organelle:

Nucleus: The nucleus is a membrane-bound organelle that houses the cell's genetic material and controls cellular activities, including growth and metabolism.

Ribosomes: Ribosomes are small, non-membrane-bound structures composed of RNA and proteins that synthesize proteins by translating messenger RNA.

Endoplasmic Reticulum (ER): The endoplasmic reticulum is a network of membranous tubules and sacs that assists in the synthesis, folding, modification, and transport of proteins and lipids; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Golgi Apparatus: The Golgi apparatus is a stack of flattened membrane-bound sacs that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Vacuoles: Vacuoles are membrane-bound sacs that store substances such as nutrients, waste products, and water, helping to maintain turgor pressure in plant cells.

Lysosomes: Lysosomes are membrane-bound organelles containing digestive enzymes that break down waste materials and cellular debris, playing a key role in the cell's metabolism and recycling processes.
