The chart below shows the three main types of plant tissues and associated tissues. mc003-1.jpg Which row (A, B, C, or D) best c
katrin [286]
I found the exercise on the internet. Attached is the chart and the rows. On the left we have "plant tissue", then on the middle top - "dermal" - and just below - "ground". Straight in front of "ground", the term is "c<span>ollenchyma".

The correct row would be D.
1. is vascular because that's the other type of plant tissue besides the ones that are already present in the chart.
2. and 3. - s</span>clerenchyma and parenchyma - are indeed types of ground tissues next to collenchyma.
4. and 5. - x<span>ylem and phloem - are the types of tissues present in vascular plants, they work as vessels where water and nutrients are conducted.</span>

Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of ________ and pulls sister
Veseljchak [2.6K]

Answer:

Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of "microtubules" and pulls sister chromatids apart, whereas the contractile ring is made of "actin filaments" and required for the separation of daughter cells at the end of the mitotic phase of the cell cycle.

Explanation:

The three chief organizational apparatuses of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three apparatuses cooperate with each other non-covalently. The cytoskeleton is composed of protein filaments and is found throughout the inside of a eukaryotic cell. The cytosol is the main component of the cytoplasm, the fluid that fills the inside of the cell. The cytoplasm is everything in the cell except for the cytoskeleton and membrane-bound organelles.

Why is the property of water important to organisms in Aquatic and land habitats?
lana66690 [7]

Answer:

<u>Without a water supply, organisms in aquatic and land habitats will die. Organisms without access of water cannot access oxygen, and as a result of that, they would die. Oxygen is needed for organisms in order to survive. Water also helps insulate the living environment for these organisms.</u>
