Answer:
The correct option is a. lacks organelles beyond ribosomes.
Explanation:
All cells of higher organisms are bounded by a cell membrane (also called plasma membrane or plasmalema) and contain cytoplasm that surrounds one or more nuclei. Within the cytoplasm there are structures known as organelles, which are specialized in carrying out the metabolic processes of the cell, these cells are called eukaryotes. The prokaryotes are smaller, lack a differentiated nucleus and organelles. The prokaryotic cells are not internally divided by membranous walls, but consist of a single space.
Both prokaryotic and eukaryotic cells contain ribosomes. Ribosomes are organelles not delimited by membranes, these organelles are important since a cell makes all its proteins in its ribosomes.
Answer:
Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.
Explanation:
In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
Answer: Stomata densities change in response to changing atmospheric levels of carbon dioxide. Stomata may also vary in response to the amount of annual rainfall in different localities.
