Botany

What large Organelle use stuff from an onion cell

Nucleus

What type of macromolecules do amyloplasts store?

Starch

What are chromoplast and what Colors are shown

Yellow, orange, red ,store, and synthesize

In the green leaves of plants do chromoplast exist or not if yes, why can’t we see them? When can we see their colors?

Yes, we can see them during fall. We can’t see them because they are not involved in photosynthesis.

Why do leaves turn yellow/orange colors in the fall?

Because of reduced PS activity unmasking Already Present carotenaids

What are the functions of Chromoplast

Store and synthesize

What is chloroplast? Why is it so important in plants?

An organelle in plants that is the site for synthesis. It’s also important because it helps plants photosynthesize.

Why are chlorophyll green?

Chlorophyll absorb every color, but green, which makes it reflect green

What do plastids store?

Chloroplast and chromoplast, food and pigments

name for organelles unique to plant cells

vacole, cell wall, chromoplast, chlorophill, plasmademada, plasids

Evolutionary adaptions of stone cells in pairs, (why you taste, greedy textures, eating a pear)

Because of scleraids

What is a tissue

A group of cells that have a similar structure and work together

Locate parenchyma. What are the main functions of the tissues?

Photosynthesis ,storage of nutrients ,wound healing

What type of cell wall do the parenchyma have ?

1° thin Cell wall

locate collenchyma? What are the main functions of the tissue?

Support

Do collenchyma Have secondary cell walls?

No

Where it plants do you find the collenchyma Tissues

Young/developing stems

Collenchyma has irregular cell sizes resulting in large and cellular spaces. What is this called and what is made of

Irregularly thickened cell walls / middle lamena

Can you find parenchyma When looking around collenchyma Tissues

Yas

What type of cell walls do you see in sclerenchyma

Thick secondary cell wall

Do sclerenchyma have secondary cell wall

Yes

Let’s the main components of secondary cell wall

Cellulose ,Lignin

Compare stone cells and fibers , what are the differences between the two in terms of the number of cells aggregated?

Stone cells are compact, while fiber cells are separated

Collenchyma and sclerenchyma tissues have a common main function. What is it?

Support cells

Is nati cute
