The correct answer is: Movement can occur both upward and downward in the plant.
Phloem is a plant tissue (in vascular plants) that transports the organic compounds made during photosynthesis in the form of sap-water based solution rich in sugars. Phloem is composed of living cells generally called sieve elements. Transport of sap is multidirectional: sometimes sugars made in photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots but sometimes roots are sugar sources so the sap needs to be transported upward for the plant’s growth.
Answer:
The correct answer is: C) intermediate filaments.
Explanation:
<u>Intermediate filaments are proteins present in every tissue and that are part of the cytoskeleton. </u>
Although these filaments do not participate in cell motility as microtubules and microfilaments do, they have many functions like helping maintain the integrity of two important cellular junctions: desmosomes and hemidesmosomes.
Desmosomes adhere adjacent cells together, while hemidesmosomes connect the basal epithelial cells to the basal lamina.
Green plants and algae are immobilized organism
Animalia. This is the animal kingdom, and animals do not have cell walls, only cell membranes. All other mentioned kingdoms do or might have cell walls. The lack of cell walls in animals is one of the characteristics that distinguishes which kingdom an organism belongs to.
Answer:
Systema Naturae, Linnaeus classified nature into a hierarchy. He proposed that there were three broad groups, called kingdoms, into which the whole of nature could fit. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes.
