True. The sugars made during photosynthesis in the leaves (sugar source) are transported by the means of the pressure-flow hypothesis to sugar sinks. The roots are a sink since there is a low concentration of sugar and they need more from sugar sources to grow.
No, blood is not an example of epithelial tissue. Epithelial tissue is composed of closely packed cells that line the surfaces and cavities of the body, while blood is a connective tissue composed of cells suspended in a liquid matrix called plasma.
False. Life forms can be categorized as eukaryotes and prokaryotes firstly. Eukaryotes, example your plants ,animals, protists and so on are comprised of multicellular organisms which have membrane bound organelles and then the prokaryotes, example bacteria and archaea lack these membrane bound organelles.
describe cells that have changed their shape to do a special job
False. Microscope lenses should only be cleaned using a specialized lens cleaning solution and lens paper to avoid damaging the delicate lens coatings. Using any soft tissue may scratch or leave residue on the lens, affecting the quality of the image.
False, there are some fungi-like organisms with cellulose, but true fungi do not have cellulose in the cell walls.
True
No, blood is not an example of epithelial tissue. Epithelial tissue is composed of closely packed cells that line the surfaces and cavities of the body, while blood is a connective tissue composed of cells suspended in a liquid matrix called plasma.
false
True. The sun is the ultimate source of energy for nearly all life on Earth through the process of photosynthesis, where plants and other photosynthetic organisms convert sunlight into chemical energy.
False. Organisms may have varying numbers of chromosomes. For example, humans have 46 chromosomes, while bacteria typically have one circular chromosome. Plants can have different numbers of chromosomes depending on the species.
no.or false. Members of Pteridophyta division of plant kingdom do not bear seeds but they have vascular tissues in the form of xylem and phloem. Plants below the rank of Pteridophyta (such as algae, fungi and bryophyta neither have seeds nor vascular tissue in the form of xylem and phloem).
True. Spongy mesophyll cells are found in the leaf tissue of plants and are involved in the exchange of gases necessary for photosynthesis.
ture or false do plants and amimals can cause weathering
True. Photosynthetic bacteria obtain energy by removing electrons from inorganic molecules through a process called photosynthesis. This allows them to generate ATP and ultimately produce organic compounds for their growth and metabolism.
False. Life forms can be categorized as eukaryotes and prokaryotes firstly. Eukaryotes, example your plants ,animals, protists and so on are comprised of multicellular organisms which have membrane bound organelles and then the prokaryotes, example bacteria and archaea lack these membrane bound organelles.
False. Almost all of the oxygen on Earth is found in the oceans.
False
