have chloroplasts and a cell wall (a
structure membrane) made of cellulose.exterior to the plasma
- How different are animal
cells from plant cells?
While plant cells are autotrophic, photosyntheukaryotic,etic and have (^)

not present chloroplasts nor cell wall.
- Do plants have tissue
organization and specialized
organs?
Plants have specialized organs (like
reproductive organs, roots, limbs,leaves) and differentiated tissues
(vascular tissue in tracheophytes,
support tissue, parenchyma, etc.)

into which the plant kingdom
is divided?
The kingdom Plantae big subkingdoms: the bryophytes anis divided into twod
the trachegymnosperms anophytes (pteridophytes,d angiosperms). Th (^) e
criterion for the division is the presence
or not of conductive (vascular) tissue.
