Answer 1

these helps you more bro...

Answer 2

Meristematic Tissues

Capacity to divide -

• Can divide

Cell Composition -

• Undifferentiated cells

Simple/Complex tissues -

• Always simple tissues, composing of one type of cell only

Nature of cells -

• Always Living cells

Cytoplasm in cells -

• Contains dense cytoplasm

Prominent nucleus

• Always

Pace of cell division -

• Rapid

Size and shape of cells -

• Size – small
• Shape – isodiametric
• Lumen – large

Cell arrangement -

• Compactly arranged
• No intercellular spaces

Vacuoles -

• Usually absent

Metabolic rate -

• Very high

_______________________

Permanent Tissue

Capacity to divide -

• Cannot divide

Cell Composition -

• Differentiated cells

Simple/Complex tissues -

• Can be simple or complex tissue. If complex, contains more than one type of cells

Nature of cells -

• Can be non-living(Sclerenchyma) or living(Parenchyma)

Cytoplasm in cells -

• May or may not contain cytoplasm

Prominent nucleus -

• Prominent in some cells (Parenchyma) while absent in others(Sclerenchyma)

Pace of cell division -

• Completely differentiated, do not divide

Size and shape of cells -

• Size – large
• Shape – varies
• Lumen – very narrow or wide

Cell arrangement -

• Loose in some(Parenchyma)
• Compact in some(Sclerenchyma)

Vacuoles -

• Vacuoles present in living cells. But dead cells lack protoplasm

Metabolic rate -

• Very less or no metabolism at all
