Learn about Cells (26 cards)
(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.

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
