vascular tissue
The functions of this tissue is to transport water, minerals, and sugars to different parts of the plant.
How is vascular tissue structure is adapted to its function?
The tissue is made of Xylem and Phloem. Xylem tissue transport water and minerals upwards and throughout the plant. This tissue is made of tracheids and vessels have pores and pipelines that allows minerals and water to be conducted from one tube to the other.
The phloem tissue transport dissolved minerals. It has sieves cells and tubes with numerous pores that allow substances to be with cells. sieveexcahngedadajacent
Answer:
B. the similarity in size between the cytosolic ribosomes of prokaryotes and the ribosomes within mitochondria and chloroplasts
Explanation:
Endosymbiosis explains the origin of mitochondria and chloroplast from the prokaryotes that were capable of carrying out aerobic respiration and oxygenic photosynthesis.
These prokaryotes entered the larger cells and eventually lost the ability to survive as individual organisms.
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Being semi-autonomous organelles, both mitochondria and chloroplast also have DNA and ribosomes. The ribosomes present in these organelles are of 70S type. This theory is also supported by the presence of circular DNA in bacterial cells and in the mitochondria and chloroplast.
Explanation:
a) True. The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.
b) True. Active transport requires cellular energy to achieve this.
c) False. Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.
d) True. For diffusion to work, the particles must be able to move around.
e) True. Osmosis requires energy from respiration to be carried
out.
f) False. Partially permeable membranes allow only water but not other dissolved substances to pass through.
