this presentation describes the concept of growth and development of plants in details. it explains different types and phases of growth. it also contain notes on growth rate that ie arithmetic & geometric. Growth curve and growth requirements are also well explained in this ppt. it also define differentiation, dedifferentiation and redifferentiation.
Everything about photoperiodism from scratch to smart, from the oldest models to the latest models as well as proposed one, exclusive and elusive illustrations and models for proper understanding
Gymnosperm is from the Greek “gymnos” naked, and “sperma” seeds. They are groups of vascular plants that reproduce by means of an exposed seeds or ovules. They are phanerogams according to A. W. Eichler.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

3. HYGROSCOPIC MOVEMENT:
• This is the movement of part of plant that is
caused by the influence of the change of the
water level from its cells so happens non-
homogeneous wrinkling.
• Example: the breaking of dried
Kalanchoe Pinnata fruit.
• The opening of sporangium in fern
as the cause of wrinkling annulus cells.
4.
5. Endogenous movement
(autonomic)
• It is movements that is not known yet it causes
suddenly but predicted that this motion is
caused by stimulus that comes from the body
of plant itself.
• Example:
The flowing movement of cytoplasm in cell.
The blending movement of leaf bid because of
difference of growth velocity.
6. Exogenous movement:
etionom/esionom
It is plant movement that is
caused by external stimulus.
External stimulus such as:
Light, gravity, water, touch and
chemical substances .
7. The various kind of exogenous movement in plants:
Tropism movement
Nastic movement
Taxis movement
8.
9. Phototropism :
• It is tropism movement that is
caused by stimulus of light.
• Examples
the tip of plant that
lie in the room will
bend to the direction
of incident of light.
10. Geotropism :
• It is tropism movement that follows earth
gravitational force.
• Positive geotropism: geotropism movement
that its direction is downwards.
• Negative geotropism: geotropism movement
that its direction is upwards.
11.
12. Chemotropism
• Tropism movement that is caused by chemical
substances stimulus.
• Example:
the movement of roots toward the
fertilizer in the soil.
13. Thigmotropism:
• It is tropism movement that is caused by
stimulus of touch to the harder thing.
• Example:
Tendril of plant movement.
14. Hydrotropism:
• It is the movement of the pant root that is
influenced by reservation of soil water.
15. Nastic movement:
• It is plant movement to stimulus, that its direction
is not determined by stimulus but by plant itself.
• Kinds if nastic movements:
1. Photonasty
2. Nictinasty
3. Thigmonasty
4. Thermonasty
5. Complex nasty.
16. Photonastic:
• Nasty movement caused by stimulus of light.
• Example:
• the opening of Mirabilis Jalapa flower
at certain time.
17. Nictinasty:
• Nasty movement that is caused by dark
condition.
• Example:
the closing of compound leaves of
Leucaena Leucocephala at night.
18. THIGHMONASTY / SEISMONASTY
• Nasty movement that is caused by stimulus of
touch.
• example:
the closing of Mimosa Pudica when touched
19. THERMONASTY:
• Nasty movement that is caused by temperature
stimulus.
• Example:
tulip flower will bloom if the temperature
rises.
20. COMPLEX NASTY:
• Nasty movement caused by several factors all
together.
• Example:
• the opening and closing of stomata is
influenced by light , chemical substances , and
water.
21.
22. TAXIS MOVEMENT:
• Transfer movement of all parts of plants to
stimulus that its direction is determined by
stimulus.
• Kinds of taxis movements
• Photo taxis
• chemo taxis
23. Photo taxis:
• Taxis movement that is caused by stimulus of
light.
• Example :
• the movement of the chlorophyll to the
surface of the leaves to get the light.
24. CHEMO TAXIS:
• Taxis movement that is caused by chemical
substance stimulus.
• Example:
• movement of spermatozoid of moss
and fern to ovum that is found in
archeogonium attached to the sugar or protein
that is produced by archeogonium .
