Biology Flashcards
would be found in plant cell but not in a bacterial cell
Endoplasmic reticulum
the most significant difference between prokaryotic and eukaryotic cells?
Eukaryotic cells have membrane-bound organelles; prokaryotie cells do not.
can only be found in a eukaryotic cell?
Mitochondria
what organelles is involved in the cleaning up of worn-out organelles and foreign particles in cells?
Lysosomes
characteristics of an organelle
they are subcellular structure
8 From which cell organelle are nucleic acids absent?
Ribosome
10 Organelles involved in energy conversion in cells are
chloroplast, mitochondrion
16 What is the main purpose of stratification in epithelial tissues?
Protection
pairs of structures distinguish a nerve cell from other types of cell?
C Cell body and dendrites
Which of the following connective tissues consists of cells in a fluid matrix?
Blood
In a phospholipid bilayer, the
D phosphate heads are oriented towards the exterior of the cell or towards the cytoplasm
the major function of the plasma membrane do not include
recognition and communication between different cells and and tissues
Cell products are secreted from the cell through
exocytosis
Which of the following is the longest stage in the cell cycle?
Interphase
the correct sequence of phase in interphase
g1, s, g2
The longest phase in the cell cycle is
G1
The correct sequence in mitotic division
prophase metaphase anaphase telophase
During which of the following stages of interphase, does the chromosome consisting of two chromatids join at the centromere?
s, g2
When does synapsis occur in meiosis?
prophase 1
8 When does crossing over take place in meiosis?
prophase 1
9 During which stage of mitosis is a structure called the spindle formed?
prophase
in animal cell, the formation of spindle is controlled by a pair of organelle
centrioles
11 The end result of meiotic division is
four daughter cells
12 Homologous chromosomes
occur as pairs and contain the same
genes
