The four phases of growth curve are
lag phase, log phase, diminishing phase and steady phase
.
What are the 4 phases of growth?
There are four distinct phases of the growth curve:
lag, exponential (log), stationary, and death
.
What are the two phases of plant growth?
Plants have two distinct stages in their lifecycle:
the gametophyte stage and the sporophyte stage
.
What are the types of plant growth?
- Bending toward a light source (phototropism).
- Downward root growth in response to gravity (geotropism).
- Promotion of apical dominance (the tendency of an apical bud to produce hormones that suppress the growth of the buds below it on the stem).
- Flower formation.
What is growth explain types of growth?
Growth is
the irreversible increase of an organism's size over a given period
. It may also be defined as one of the characteristics of a living thing. In biology, “biological growth” is associated with progressive development. An organism's growth may go on throughout its life, or end when that species is fully mature.
What are the 4 things bacteria need to grow?
- Food (nutrients)
- Water (moisture)
- Proper temperature.
- Time.
- Air, no air, minimal air.
- Proper acidity (pH)
- Salt levels.
What is the life cycle of a bacteria?
The bacteria life cycle consists of the
lag phase, the log or exponential phase, the stationary phase and the death phase
. Factors that influence bacterial growth bear heavily on this cycle.
What are the 3 phases of growth?
They undergo three general growth phases:
vegetative, reproductive, and ripening
.
What are the 5 stages of plant life cycle?
There are the 5 stages of plant life cycle. The
seed, germination, growth, reproduction, pollination, and seed spreading stages
.
What are the 5 steps of germination?
Such five changes or steps occurring during seed germination are:
(1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators
and (5) Development of Embryo Axis into Seedling.
What is this growth called?
Apparent growth
is an irreversible increase in mass or volume of cells in plants. It is an external manifestation of growth.
What is difference between primary and secondary growth?
Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two
lateral meristems
, called the vascular cambium and the cork cambium. Not all plants exhibit secondary growth.
What are the four types of plant hormones?
Plants produce a wide variety of hormones, including
auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides
.
What are examples of growth?
Growth is defined as a gradual development in maturity, age, size, weight or height. An example of growth is
a wild teenaged girl becoming much calmer in her late twenties
. An example of growth is a boy getting an inch taller between the ages of 14 and 15.
What are the two types of growth models?
The equation above is very general, and we can make more specific forms of it to describe two different kinds of growth models:
exponential and logistic
. When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth.
What are the basic of growth?
Growth is a generic term that describes processes in which the mass of a body changes over time. In biology, the problem of growth is
fundamental to all aspects of life
, with realizations as diverse as cell division, morphogenesis, development, maintenance, cancer, and aging.
