Chapter 4 - Growth And Division Of The Cell Flashcards
Learn about Cells
(identification) Cells are initiated by division of a mother cell, grow for a period, and usually “die” by _____________ to produce 2 daughter cells.
Dividing
(identification) Plant cells experience “_____________” cells stop dividing and enter a period of growth.
Cell cycle arrest
(identification) Some cells never stop dividing. [Place]
Root tips, shoot tips, cambium.
(identification) longest phase in the cell cycle; composed of the G1, S, G2 phase.
Interphase
(T/F) G1 Phase is all about Cell Growth.
True
(T/F) S Phase is about the DNA duplication. The chromosomes duplicate.
True
(T/F) G2 Phase - Growth and Preparation for Cell Division.
True
(T/F) Length of cell cycle varies depending upon the type of cell, the type of plant, its health, age, temperature, and many other factors.
True
(T/F) G1 phase is generally the longest phase of the cell cycle.
True
(identification) Process of cell duplication, resulting to a sister chromatid.
Replication
(identification) Division of the Cytoplasm
Cytokinesis
(identification) 2 Sets of chromosomes present in a diploid nucleus are separated into the daughter nuclei.
Reductional Division
(identification) [Reproductive Cells] ________ in animals and some algae and fungi, __________ in plants and other algae, fungi.
Gametes, Spores
(identification) [Reproductive Cells] It only occurs in the ________ and __________ in seed plants.
Stamens, ovaries
(identification) [5 Stages of Prophase] chromosomes appear long and thin, nucleolus has distinct nucleolus.
Leptonema
(identification) [5 Stages of Prophase] homologous chromosomes come together to form a pair. (Synapsis)
Zygonema
(identification) [5 Stages of Prophase] paired chromosomes are closely associated and appear as one.
Pachynema
(identification) [5 Stages of Prophase] Synapsed chromosomes or bivalent breaks and exchange segments - Crossing Over
Diplonema
(identification) [5 Stages of Prophase] Bivalents attain maximum contraction and are distributed throughout the nucleus.
Diakinesis
(identification) Chromosomes exchange Bivalent genetic material and it is called _____________.
Cross-Over
(T/F) Mitosis is for growth, tissue repair and asexual reproduction.
True
(T/F) Meiosis is for sexual reproduction
True
(identification) ___________ specializes on producing new protoplasm
Shoot tips
(identification) Collect solar energy by photosynthesis
Green Leaf cells
(identification) Transport water, minerals, and organic molecules.
Vascular cells
(identification) For protection, produce poison
Epidermal Gland Cells
