complex permanent tissue types (2)

meristematic tissue

made up of small, densely packed, thin wall cells that divides to produce new cells

Vacuole

Meristematic tissues lack ________

storage of water

support

meristematic tissues lack vacuoles because they don’t need _____________

growth

meristematic tissue is responsible for _________

Apical Meristem

present in the tips of the shoots and the roots

unilateral growth

apical meristem is responsible for __________

one direction growth

unilateral growth

vertical growth

primary growth is aka __________

height

apical meristem is responsible for increasing the _________ of plants

Differentiation

the process of taking up a permanent shape, size, and function

Lateral meristem

responsible for secondary growth or horizontal growth

width

lateral meristem is responsible for increasing the ________ of plants

Intercalary Meristem

responsible for regrowth of plants

Permanent tissues

formed by the differentiation of meristematic tissues

Vacuoles

What will grow in the permanent tissue?

95%

In permanent tissue, vacuoles will grow and possibly fill _____ of the chloroplast

Parenchyma Tissue

found in most edible portions of fruit

parenchyma cells

the most abundant cell

Parenchyma Tissue

has large vacuoles and contains secretions

chlorenchyma

parenchyma + chloroplast

Photosynthesis

when parenchyma is added with chloroplast, it can do _______________

parenchyma without chloroplast

stores food and water instead of photosynthesis

Aerenchyma

parenchyma that has gaps

submerged

aerenchyma gives the ____________ plants access to air

Living cells

parenchyma and collenchyma

Sclerenchyma Tissue

has thick & tough secondary wall

Sclerenchyma cells

makes up the sclerenchyma tissue

Sclerenchyma Tissue

can also be found in the veins of the flower, and hard covering of seeds

lignin

Sclerenchyma is tough because it is embedded with ____________

thick and tough

the secondary wall of sclerenchyma tissue is

Complex Tissues

a combination of two or more simple tissues

Xylem tissues

pipes where water flows

Xylon

greek term for wood

upward

direction of water in xylem

tracheary elements

vessels + tracheids

responsible for transport of water and minerals

tracheids vs vessels

tracheids: small diameter, no perforations, shorter

vessels: broader diameter, perforations all over, longer

fibers

support

tracheids

found in vascular plants

tracheids or vessels?

vessels

found in angiosperms (flowering plants)

tracheids or vessels?

Phloem

greek work for bark

Phloem tissue

transports food to the plant up and down

leaves

the kitchen of the cell

Epidermal Cell

outermost layer of cells

cutin

forms cuticle

a fatty substance secreted by epidermal cells

Cuticle

basis for loss of water by evaporation

provides resistance to bacteria

surface area

Epidermal cells increase the ________________ of root hair to increase absorption

stomata

pores in leaves

guard cells

guards stomata

a unique epidermal cell, contains chloroplast
