Answers


What are the different organs that are found in plants? - CORRECT
| | | | | | | | | | | |



ANSWER✔✔-Roots, Stems, and Leaves (Shoots) | | | |




What are the different tissues that are found in plants? - CORRECT
| | | | | | | | | | | |



ANSWER✔✔--Dermal (blue) | |




-Vascular (purple) | |




-Ground (yellow) |




What are the different cell types that are found in plants? - CORRECT
| | | | | | | | | | | | |



ANSWER✔✔--Parenchyma
-Collenchyma
-Sclerenchyma
-Water-conducting cells of the xylem | | | | |




-Sugar-conducting cells of the phloem| | | |




What is the function of each organ found in plants? - CORRECT
| | | | | | | | | | | |



ANSWER✔✔--Roots = Anchor the plant, absorb minerals and water,
| | | | | | | | |



store carbohydrates
| |

,-Stems = Move nutrients upward
| | | |




-Leaves = Intercept light, Exchange gases, Dissipate heat, Defend the
| | | | | | | | | |



plant from herbivores and pathogens
| | | |




What is the function of each tissue found in plants? - CORRECT
| | | | | | | | | | | |



ANSWER✔✔--Dermal = the epidermis (cuticle: prevents water loss) | | | | | | |




-Vascular = Transports resources and provides mechanical support
| | | | | | | |




-Ground = specialized for storage, photosynthesis, support, short-
| | | | | | |



distance transport |




What is the function of each cell type found in plants? - CORRECT
| | | | | | | | | | | | |



ANSWER✔✔--Parenchyma = Least specialized, carry out most metabolic | | | | | | |



functions
|




-Collenchyma = Provide flexible support to growing parts of shoot
| | | | | | | | | |




-Sclerenchyma = Provide rigid support, highly lignified, dead at maturity
| | | | | | | | |




-Water-conducting cells of the xylem = conduct water | | | | | | |




-Sugar-conducting cells of the phloem = conduct sugars | | | | | | |




What are meristems? - CORRECT ANSWER✔✔-Perpetually embryonic
| | | | | | |



tissue and allow for indeterminate growth
| | | | |




Where are meristems located? - CORRECT ANSWER✔✔--Apical = the
| | | | | | | | |



tips of roots and shoots
| | | | |

, -Lateral = On the stems of the plant (vascular and cork cambium)
| | | | | | | | | | |




What is the meristems' function? - CORRECT ANSWER✔✔--Apical =
| | | | | | | | |



elongate shoots and roots, a process called primary growth
| | | | | | | | |




-Lateral = add thickness to
| | | | |




woody plants, a process called secondary growth
| | | | | |




What is primary and secondary growth? - CORRECT ANSWER✔✔--
| | | | | | | |



Primary = When apical meristems elongate shoots and roots
| | | | | | | | |




-Secondary = When lateral meristems add thickness to woody plants
| | | | | | | | |




What tissues are involved in each type of growth (primary and
| | | | | | | | | | |



secondary)? - CORRECT ANSWER✔✔--Primary = Dermal and vascular
| | | | | | |




-Secondary = Vascular (cork and vascular cambium)
| | | | | |




What is the importance of cell division in establishing polarity in plants?
| | | | | | | | | | |



- CORRECT ANSWER✔✔-It is the condition of having structural or
| | | | | | | | | | |



chemical differences at opposite ends of an organism (i.e. root end and
| | | | | | | | | | | |



shoot end of plant)
| | |




What is asymmetrical cell division and why is it important? - CORRECT
| | | | | | | | | | | |



ANSWER✔✔--When one daughter cell receives more cytoplasm than | | | | | | | |



the other during mitosis
| | |
